A2.0-ohm resistor is connected in a series with a 20.0 -v battery and a three-branch parallel network with branches whose resistance are 8.0 ohms each. ignoring the battery’s internal resistance, what is the current in the batter? show your work.

Which type of wave can travel without a medium

Lightning is an example of what phenomenon? a release of a large amount of energy an absorption of a large amount of energy a natural electric circuit a natural electric current

Ametal ring 4.20 cm in diameter is placed between the north and south poles of large magnets with the plane of its area perpendicular to the magnetic field. these magnets produce an initial uniform field of 1.12 t between them but are gradually pulled apart, causing this field to remain uniform but decrease steadily at 0.240 t/s . (a) what is the magnitude of the electric field induced in the ring? (b) in which direction (clockwise or counterclockwise) does the current flow as viewed by someone on the south pole of the magnet?
